So, you've installed CCCP but your anime still doesn't play, or plays but with problems? No worries, here's a list of common problems and a basic troubleshooting guide, and if it still doesn't work you can always ask in #CCCP.
Step-by-step troubleshooting guide
So, you downloaded the CCCP, followed the installation instructions, and it still doesn't work? Well, there are a bunch of things that can cause problems. This is a step-by-step guide to try to fix playback for you. Note that these instructions are meant to be used when NOTHING works. If you have problems with a single file, or a single type of files, read about the specific problems below.
- First, make sure you have installed the CCCP correctly. If you missed the instructions on the main page, here's how to do it:
- Download the pack. (duh.)
- If you know for certain that you do not have any other codec packs currently installed you may skip this step. Otherwise if you are unsure if you have other codec packs installed follow these instructions : Download CCCP Insurgent (CCCPI) (see below) and run it. The Codec/Filter Packs list should be filled with any codec packs that you currently have or might have had installed at one time on your computer. Go to Start -> Control Panel -> Add/Remove Programs and uninstall all the packs that were listed by CCCPI. Those that are marked with Uninstalled are no longer on your computer, so don't look for them. Confirm with "Yes to all" if you are asked whether to delete certain files or not. If you are asked whether you want to reboot then reboot, but after that come back to the Add/Remove Programs list and continue removing any packs listed as Installed. Do not touch the "Register Filter" and "Unregister Filter" buttons!
- Uninstall all other individual codecs and filters (like DirectVobSub, ffdshow, CoreVorbis, CoreAAC, etc.) You can keep DivX or Xvid if you want to, or if you plan on encoding with DivX or Xvid. They won't interfere with CCCP, so don't worry. You can also uninstall them now and install them after CCCP, it doesn't matter. However, they won't be used for decoding unless you change some settings - read about it here. CCCP is only a playback solution, so that is why you need to have DivX or Xvid if you plan on encoding in those formats. Note: do not touch anything you didn't install yourself, or anything you're unsure about. When in doubt, ask in #cccp or on the forums.
- Reboot. IMPORTANT! Don't skip it because you are lazy.
- Install the CCCP. Be sure the Reset all settings option (at the end of the installation) is checked. If you are interested in changing the default settings, read the FAQ's and other documentation below.
- Try reinstalling the CCCP, often this will fix the problem.
- If it's a file you are still downloading, make sure the download finishes before trying again. This is especially important for BitTorrent downloads - those are NEVER finished until the WHOLE torrent download is finished, no matter what it looks like!
- If it's just one or a few files that are having problems, try verifying that they are not corrupted by CRC-checking them, as described below.
- Make sure you're using one of the supported players - one of the two that comes with the pack. If you had one of them installed before, DO NOT USE IT. Use the one that the pack installs for you. Other players may work as well (see the CCCP and players page), but we can't guarantee it.
- If it doesn't work in the players that come with the pack, check if you have DirectX 9 or later installed. If this doesn't make any sense to you, or if you aren't sure if you have it or not, just get the latest version from Microsoft. You can find it here.
- If it still doesn't work, try updating your drivers, especially the graphics and audio drivers.
- When all else fails, read about how to draw a graph in GraphEdit below, draw the graph, take a screenshot of it, fire up your IRC client and join #CCCP on irc.rizon.net. We are there to help you.
Below follows a list of some specific problems, and solutions to them.
Basic troubleshooting conceptsQuickSFV or FlashSFV, install one and then double-click the SFV file. The files must have their original names and the SFV file must be in the same directory.
If no SFV file can be found, the CRC can sometimes be found in the filename, for example:
In this case, CB2EDC1E is the CRC checksum. The CRC is often inside brackets, and is always 8 characters long, with all characters being hexadecimal values (that is, they must be one of 0123456789ABCDEF).
To check it against the file, we suggest that you use the CCCP Insurgent to check the CRC. Simply goto Tools-> CRC Check, select the file, and compare the reported CRC against a known value. Another good place to locate CRC values is AnimeDataBase.
If the file turns out to be corrupted you can: patch it with Zidrav, use PAR2 files, or restart the torrent on the file. These are all the easiest ways to fix a corrupted file because it does not involve re-downloading the entire file. Which should be the last option.
Conflicting codecs and the CCCPI
If the file is verified and playback still doesn't work, it's time to start looking for other codec packs and/or codecs that might conflict with the CCCP in some way. The simplest way to do this is to use the CCCPI and a reinstallation. A correct (re)installation procedure goes like this:
- Use the CCCPI to find any old codec packs (Matroska pack, K-Lite, Nimo etc.). If a pack is listed with "Uninstalled" that means you had the pack in question installed once before, but it is now uninstalled. DO NOT TOUCH THE "Register filter" AND "Unregister filter" BUTTONS!
- Uninstall ALL codec packs that the CCCPI lists as "Installed": FFDShow (important!), VobSub, and anything else codec-related you might have on your computer, including the CCCP. Use Control Panel -> Add/Remove Programs to find and uninstall them properly.
- Reboot. IMPORTANT.
- Install the CCCP.
- After the initial installation you will be prompted with the question Do you want to reset all settings for the installed programs? Be sure to select Yes to this.
Getting rid of old FFDShow versions
Sometimes, FFDShow or packs that install it will "forget" a ffdshow.ax file somewhere on your computer. A common problem when you have this issue is the player crashing with an exception pointing to ffdshow.ax. To get rid of the old ffdshow, you have to find it, unregister it and delete it. Like so:
- Go to Start -> Find -> Files or folders...
- Search for ffdshow.ax on your local harddrives.
- If you find it anywhere else than in your Program Files\Combined Community Codec Pack\Filters directory, take note of the full path.
- Go to Start -> Run... and type regsvr32 /u "X:\path\somewhere\ffdshow.ax" - of course substituting the path for the one on your computer. Note that if ffdshow.ax is in your WinNT\system32 directory, it is sufficient to type regsvr32 /u ffdshow.ax.
- Now delete the ffdshow.ax file.
- If you found multiple ffdshow.ax's outside your CCCP\Filters directory, repeat these instructions once for each file.
- Playback should now work.
Resetting everything to CCCP defaults
This might be useful if you changed something in the settings and playback stopped working, but you can't remember what it was that you changed.
- Go to Start -> Programs -> Combined Community Codec Pack and open the Settings manager.
- Press "Next" to get to the second page.
- Under "Special Settings", check "Reset All Settings".
- Press Apply.
- Select Yes to the question, and follow through the Settings until Apply is hit again.
All CCCP components should now have their default settings restored.
Asking for help checklist
If you're unable to solve the problems yourself, you're welcome to ask in #CCCP. Before asking, we ask you that you are prepared with the answers to some questions that we will almost always ask you:
- Test if it works in one of the supported players (ZoomPlayer or Media Player Classic) first.
- If the file is still downloading, wait until it's finished before trying again.
- Always check if you're using the latest version of CCCP. If not, update.
- Group and series of the non-working file - preferably exact filename too.
- If other files of the same type work or not.
- The exact text of any error messages.
- A detailed description of the problem.
- What things you've already done to try to solve the problem.
Common video problems
The Video is slower than the audio! (or any audio/video/subtitle desync)
Number 1 cause: you are trying to play high definition h264 on a CPU that's too slow. There are two solutions: upgrade your CPU, or use a more efficient decoder:
- Faster CPU: Find a faster CPU that is supported by your mobo, or upgrade the entire computer. Note that no other component really matters. A GeForce 10000GX3 will give no benefit over an Intel GMA945 in terms of decoding speed (unless you use a decoder especially designed for GPU-assisted decoding).
- Faster decoder: The standard h264 decoder in CCCP is ffdshow. It uses libavcodec, which is the standard free h264 decoder. There are faster decoders, see LAV video decoder (tick LAV Video in CCCP Settings), CoreAVC, GPU-assisted decoding (included in MPC-HC & PowerDVD).
If you have a dual/quad core CPU, in ffdshow video decoder configuration, under Decoder options, set the Number of decoding threads to the number of processor cores you possess, as it defaults to 1 (no multi-threading).
The screen is completely black!
Some users have had trouble with going fullscreen when using certain Windowblinds or other skinning utilities themes, you should try disabling the theme. A skin known to cause this problem is StealthOS. You can disable the skin only for the media player you use by adding an exclusion in the 'per application settings' section of the Windowblinds settings.
Another cause is strange overlay values set by weird programs, which you can reset by:
- Start playing a video in Media Player Classic (the player that comes with the CCCP, not Windows Media Player)
- Open up your video card control centre/panel (usually found in Control Panel->Display->Settings->Advanced->(your video card/control centre tab) and setting your overlay values to defaults (ie brightness, contrast, hue, saturation, gamma, and occasionally other values).
It has been reported, that Miro, while working in the background, can cause screen blackness in ZoomPlayer. Should this happen to you, simply shut Miro down, or use MPC.
Overlay Mixer doesn't load
You have Overlay Mixer selected as the video renderer in your player, but it doesn't appear to be used (for example, it is not listed under the Play -> Filters menu in MPC-HC). This could be caused by several things:
- Some other program is already using the video overlay: Most video drivers/hardware allow only one overlay at a time. Try exiting all other non-essential programs, especially video-related ones.
- The video window is not on the primary display: On some systems you can only use the overlay on the primary display. Check the Settings tab of Display Properties (from the Control Panel for example) to confirm the one you're trying to use is set as primary.
- Hardware acceleration features are disabled on the system: The video overlay is used through DirectDraw, and it requires hardware acceleration to be enabled. Check the Display tab in dxdiag (DirectX Diagnostic Tool), DirectDraw Acceleration should be Enabled. If it says Not available or similar then go into the Display Properties, and on the Settings tab press the Advanced button. In the newly opened window check the Troubleshoot tab, the Hardware acceleration slider should be set high enough that DirectDraw acceleration is not disabled (preferably to Full).
- Video drivers are not installed or otherwise broken: You need working video drivers from the manufacturer of your hardware. If you have already installed them previously, you can try re-installing or installing a different version altogether.
It looks stretched! (or what does anamorphic mean)
This means you're trying to watch an anamorphic encode using a player that doesn't support aspect ratio correction or that VSFilter is trying to extended the image to 4:3 (which it does with the default setting, if you installed it separately - the CCCP version does not do this). Set it to "original" image size and use a player/decoder which supports it to fix the problem.
Many newer MKV encodes are anamorphic which means that the pixels themselves do not have a 1:1 aspect ratio. The videos are resized to the proper PAR, pixel aspect ratio, on playback. This allows encoding without having to resize the source which keeps a lot more detail, especially for 16:9 movies.
To solve the problem, install the pack and use one of the players that comes with it (MPC or ZP).
There is a glitch in video and I have to manually seek for it to start playing!
Most encodes are accompanied with a SFV file. This file contains information which will allow a file to be identified exactly. Start by checking the file. If the checksum fails it means either your file is corrupt or incomplete. Compare the filesize of your file, in bytes, against the original. If the filesizes are the same you can simply ask someone for a patch. If the checksum matches the file, however, you are either using a buggy filter somewhere, or there is a problem with the file itself.
How do I make DivX stop playing all MPEG-4 or DivX files?
To make DivX stop trying to decode things like Xvid uncheck "Support Generic Mpeg4" in the decoder configuration's "Quality settings" tab. This will allow you to use other decoders. Making DivX stop decoding DivX in the latest version requires that you completely unregister it. Run
regsvr32 /u divxdec.ax
to unregister the decoder and then
if you ever want to use it again.
It looks blocky or generally odd, what do I do?
First make sure that you're using the hardware overlay, sometimes it won't be used because of too little available memory on the graphics card or because another player is already open. This becomes very evident with 100% usage and bad image quality no matter how fast your computer is. This can sometimes be fixed by using a 32 bit colordepth and reducing the resolution on the desktop.
There is another issue in recent DivX versions that makes blocks appear in 5.0.x encoded movies. The solution is to upgrade to ffdshow. If it's a lavc encode and looks bad (colors shifting towards pink) you should also switch to ffdshow.
If you are trying to play a 10-bit/Hi10P H.264 video, make sure you have CCCP 2011-07-30 or newer installed - preferably the latest version of the Combined Community Codec Pack installed.
All colors look completely wrong when playing WMV video!
If you have an ATi video card, this is caused by the driver trying to accelerate WMV decoding and failing. You need to disable it. With newer ATi drivers, this can be done several ways.
Catalyst Control Center:
- Start the Catalyst Control Center.
- Click "View -> Advanced View".
- Go to "Video -> All Settings".
- Scroll down to the bottom.
- Uncheck "Windows Media Video Acceleration".
- Click "Apply".
- Close the CCC and reboot your computer.
ATI Tray Tools:
- Right click on the ATI Tray Tools icon in the system tray.
- Go to "Tweaks", click on "Standard Tweaks".
- Click the System tab.
- Uncheck "WMV Acceleration".
- Click "Apply".
WMV video should now work properly.
If you have an older ATi driver that doesn't use the Catalyst Control Center, and you aren't using ATI Tray Tools, you'll find the WMV acceleration setting in the Windows Desktop properties:
- Right-click the desktop and click "Properties".
- Click the "Settings" tab.
- Click the "Advanced" button.
- Here, find a checkbox called "WMV9 acceleration" or something like it. Uncheck it.
- Click OK, and reboot your computer.
The colors should now be correct.
Other tweak programs (e.g., Rivatuner) should have controls for this as well. More solutions are welcome!
The image is completely screwed - double, upside down and cut in half!
This is a rather random problem. Sometimes, something as simple as a reboot or a reinstall of CCCP solves it. Try that first, but if it fails a pretty reliable fix seems to be to turn on YV12 output in ffdshow (Start -> Programs -> CCCP -> ffdshow video decoder configuration -> output -> check YV12). Another thing you can try if that doesn't work is switching your graphics drivers. If there's a newer version available, get that, but if not, downgrade one version (note: on nVidia 6xxx and 7xxx cards, this problem seems to happen much more often with 9x.xx series drivers than with 84.xx). If that doesn't work either, try switching output renderers in the player or updating DirectX. If it STILL doesn't work after that, join the IRC channel for further assistance.
Owners of 8800 series video card seem to experience driver issues with YUY2 color space (CCCP sets ffdshow to output video in YUY2 for any video format). The upper right corner of the image looks like it's flipping, or something similar. The solution is to enable ffdshow to output video in YV12. To do this, go to ffdshow video decoder configuration -> Output -> place a check on YV12 -> Ok. The future CCCP packs (after 2007-02-22) will have YV12 enabled by default.
If you have a black/weird color image, please reset your overlay color values as follows:
Important note: Please do this while a file is playing in the background, otherwise you might not be able to access the overlay color sliders !
- Go to "Display Properties -> Settings [Tab] -> Advanced [button] -> GeForce xxxx [Tab] -> Color Correction"
- Change the Apply Color Changes [drop down] to Overlay
- Change Brightness [slider] to 100% and Contrast [slider] to 100%
- Click Apply
- Go to "Display Properties -> Settings [Tab] -> Advanced [button] -> GeForce xxxx [Tab] -> Video Overlay Settings"
- Change Hue [slider] to 0 and Saturation [slider] to 100%
- Click Apply
- Click OK and OK again.
Mainly the WMV9 decoding acceleration one - see above.
Windows 2003/XP x64 and black screen(sound but no video)/grey screen/weird colours
Symptoms: any of the following ones:
- you are using ZoomPlayer, irrespective of having Colors Controls enbled or not
- you have enabled ffdshow's Overlay Control
- you are using any other player that allows you to change the overlay colour values regardless of having enabled that option or not.
When you close the player and start it, or any other player, again, you may experience either a black screen (aka sound but no video), a grey screen or the colours look completely weird.
This is a problem with Windows 2003 and with XP64 themselves. When you close the player, the overlay colour values are set to absurd values (like -100 brightness and so on).
Solution: To overcome this problem, there's not much you can do. First of all, make sure Overlay Control is disabled in ffdshow's Video decoder configuration settings (the Overlay option is unchecked in the list on the left)
1) Stick to only MPC or only ZoomPlayer. Using Zoomplayer and then MPC will give you a black/grey/weird colours screen in MPC. That's why only was emphasized.
If your favourite is ZoomPlayer, then you need to do this: open a file in ZoomPlayer -> open your graphic card's overlay control page and reset the values to defaults as described below in the How to reset to Default Overlay Values -> right click on the video surface -> select Options/Setup -> go to advanced mode by pressing the Advanced Mode button -> select Colors Control in the list -> check Use Color Control Interface -> press the Query Overlay button -> in the Confirmation dialog that pops up select Ok -> press Set Current as Default -> press Manual Save -> press Close. (If you are wondering what this does: each time ZoomPlayer is closed the overaly values are broken, but by enabling the Color Control Interface, the right values that you have saved as defaults are restored each time ZoomPlayer is opened)
2) If you like to switch between players or use other players not supported by CCCP, then you will sooner or later get the black/grey/weird colours screen. Each time this happens, just reset to the default overlay values as described below in the How to reset to Default Overlay Values.
How to reset to Default Overlay Values:
For ATI graphic cards: start the playback of a media file if you have no file playing already -> right click on the desktop -> Properties -> Settings -> Advanced -> Overlay -> press the Defaults button -> use the other sliders to adjust the colours to your liking -> press Apply. (KoD note: someone should write how to do this from within the Control Center)
For NVIDIA graphic cards: start the playback of a media file if you have no file playing already and then see the last paragraph of the nVidia Issues entry for instructions on how to adjust the color controls.
Each time you need to change the colours while playing, you have to use the overlay colour controls provided by the driver of your graphic card as written above.
Note: Zoom Player v4.00 does not interfere with the nVidia 84.25 driver overlay settings (XP x64). (Unsure what features are being lost compared to v4.51)
After installing PowerDVD 7 H.264 playback is broken!
PowerDVD 7 hijacks all video and completely unregisters the CCCP. There is a solution for this, though. It is fairly simple:
- 1. Run the CCCP Insurgent
- 2. Find the Cyberlink H.264 decoder in the filter list (CL264dec.ax), highlight it and click "Unregister filter"
- 3. Run CCCP Settings
- 4. On the second page of the config, choose to re-register all filters. Apply the changes
If playback is still broken after this, go to the CCCP IRC channel.
Common audio problems
Voices are really low!, or, how I learned to stop worrying and love the centre channel
If files that comes with 5.1 audio (does the file not have 5.1 audio? this isnt the solution then) have very quiet voices, by far the most common cause is that the centre channel is not being mapped to the centre channel properly. Look on this page: Issues:No Centre Channel
I found out that the ffdshow's 32bit floating point output doesn't send data properly to the center speaker. Disabling the 32bit floating point ouput should fix the problem of having very low volume for voices (which are often played over the center channel).
The volume is really low in some files!
Have a look at the Files with Dolby Digital AC3 or DTS audio entry on this page to see if it can help you: Issues:Low Volume
What causes the audio to stutter?
If the audio plays, but cuts out or "hiccups" every few moments, there are a few common problems that can cause this:
- Your CPU is not fast enough to play the media properly. You can try disabling the Matrix Mixer (see "Mixer" in the "ffdshow audio decoder configuration" window). A slow computer can cause audio problems even if the picture displays properly.
- The player is not using the ffdshow decoder for the type of audio that is in your file. For example, Nero comes with a decoder that doesn't work properly in our tests, and if its priority is higher than ffdshow's it will be used instead.
- FFDShow might have problems playing badly encoded MPEG-4 audio. This can cause stuttering sound over an optical or digital-coaxial connection, and even no sound at all from the analog sound card outputs. If you encounter this problem with files containing AAC, AAC+, HE-AAC, SBR-AAC, MPEG4, or MP4A audio types, you could try using CoreAAC (available on this page) instead. Add the filter to your player's preferred list, then find the "Codecs" page in ffdshow audio's configuration window. Beside "AAC" in the Format column, change the Decoder from "libfaad2" to "disabled". Don't forget to change it back when you're done watching, and please note that CoreAAC only supports analog output.
- Some have also experienced audio stutter with ffdshow audio decoder's equalizer enabled.
Vorbis audio crackles and sounds really evil! How do I fix it?
This can be caused by two things, the first being decoding Vorbis with tremor instead of libavcodec in FFDShow, the second using the WaveOut device in the player (starting from CCCP5 (2005-09-23), the installer sets the audio output device to DirectSound automatically for you). These are solved as follows:
Setting Vorbis decoding to libavcodec
- Open the FFDShow Audio Settings (Start -> Programs -> Combined Community Codec Pack -> FFDShow Audio Decoder Config).
- In the list to the left, click the Codecs entry.
- Now, in the codec list to the right, click the Vorbis decoder entry and choose libavcodec from the dropdown menu.
- Press OK and you're done.
Changing audio output devices
- In Media Player Classic:
- Open MPC and go to the View menu, then click Options.
- In the tree view to the left, go to the Playback -> Output entry.
- Under the "DirectShow Audio" heading, choose "Default DirectSound Device" from the dropdown menu.
- Press OK and restart MPC. Done.
- In ZoomPlayer:
- Open ZoomPlayer, right-click the video surface and go to Options/Setup.
- Make sure you are in Advanced Mode by clicking the Advanced Mode button in the bottom left corner. If it reads "Basic Mode", you are already in Advanced Mode.
- Go to the Filter Control section and choose the Standard Media Playback tab.
- Under Custom Audio Devices, select "Default DirectSound Device".
- Check the checkbox below marked "Use Custom Media Audio Device"
- Press OK and restart ZoomPlayer. Done.
How do I get it to output multichannel audio?
Make sure that downmixing isn't set to 2/0 in the CCCP Settings Manager (first page - see the settings manager FAQ entry for more information). This will give you 5.1 audio if the file contains it and you've chosen the appropriate stream.
If your speaker configuration isn't 2.0 or 5.1 you might want to use the downmixing option in FFDShow's audio decoder. To do this, go to Start -> Programs -> Combinined Community Codec Pack -> FFDShow Audio Decoder Settings -> Mixer and set the appropriate number of speakers. Then check the box marked "Mixer" and press OK.
I can't seek!
If the total time is displayed as 00:00 in ZoomPlayer (or any other player) you need to update the Matroska splitter you're using to the latest Haali Media Splitter. This only affects releases from around September 2004. Install the latest pack and be happy.
If your MKV has no frame index part or corrupted, this might lead this error too. Use Meteorite tool for repair your MKV file.
I randomly get no audio or no video when I play MP4's. Now what?
In 99% of all cases, this is caused by Nero's MP4 splitter (NDparser.ax) interfering. Most users have a working version of it, and then you usually never notice it since it just works (you won't get Haali's tray icon though). However, for some, seemingly random, users it's broken and doesn't provide either video or audio output. The solution to this problem is to unregister it, after verifying that it is indeed the culprit. This is most easily done using the CCCP Insurgent.
- Start CCCPI.
- Go to Tools -> Test render... and open one of the MP4's you're having trouble with.
- In the dialogue box that pops up, look for the filename and path of the MP4 you're trying to play. It might look something like this:
Filter 2: D:\CCCP testfiles\Ergo_Proxy_00_Sneak_Preview_Vol1.mp4 Filename: C:\Program Files\Common Files\Ahead\DSFilter\NDParser.ax
- If the filename at the "Filename" heading is NDParser.ax, like in the example above, then you have Nero's MP4 splitter interfering. If not, you should NOT proceed with the following steps - you should instead ask on the forums or in #CCCP for advice.
- Close the test render window and look in the rightmost column of the Insurgent. Find an entry called "Nero Digital Parser". Make sure that the filename of it is NDParser.ax.
- Click it and then press "Unregister filter".
- Close the CCCPI. Your MP4's should now work.
I can't open some MP4 files at all!
It seems that some Sony Vaio laptops come with a bunch of more or less broken DirectShow filters preinstalled. Uninstall all Sony audio/video-related stuff you can find, but if it still doesn't work, join #CCCP for more help and information.
I tried to install the CCCP, but the installer gets stuck in an infinite reboot loop!
In theory, this should never, ever happen, but the Real World proves the theory wrong. It just happens to some people (the installer asks you to reboot to finish the installation, and when you have rebooted, it pops up first thing when Windows starts and asks you to reboot again). To fix it, just say "No" when it asks you if you want to reboot now. This will bring you into Windows at least. From here, we go on:
- Start the registry editor by going Start -> Run... and typing regedit, then pressing enter.
- In the window that pops up, there's a tree view to the left. In the tree view, find a folder called:
- In that folder, there should be a key pointing to the CCCP installer. Delete that key by clicking on it and pressing the delete button (but be careful so you don't delete anything else by accident - messing up your registry can seriously damage your Windows installation).
- You can now reinstall the CCCP, and it should no longer ask for a reboot.
This issue can also manifest itself as huge syncing problems. The same solution applies. Anyway, it's a result of incompetence on the encoders' part - it's not your, nor the CCCP's fault. Fortunately, it's a fixable issue nowadays, since Nicholi (of A-L) wrote a guide on how to fix it.
The player crashes with an exception pointing to ffdshow.ax when I open video files!
This might happen if an old FFDShow installation or a pack that installed it "forgot" a ffdshow.ax file somewhere on your computer. There's an entry in the troubleshooting guide on how to get rid of such files properly. Do NOT just delete them!
Explorer crashes when I open folders with movie files in!
Windows XP and higher
This is a known issue with Windows XP's braindead video thumbnail thing in Explorer. Being a thing invented by MS, it's buggy and doesn't always know how to handle things not supported by MS. When it sees something it doesn't like (for example, a MKV or OGM file) it occasionally crashes and takes Explorer down with it. This isn't a very funny situation to be in, but it's easy to disable it. Go to Start -> Run... and type
regsvr32 /u shmedia.dll
Press enter. Done. It's as simple as that. If you, for some reason want it back (unlikely, but might happen), simply do the same thing again, but remove the "/u". That is: Start -> Run...
This will only disable movie thumbnails/previews, not picture thumbnails.
This issue can also be caused by the thumbnail/previewer that comes with the DivX Plus codec pack.
Slightly different, and more complex process.
- 1. Go to C:\WINNT\Web
- 2. Find the hidden/system file called folder.htt
- 3. Make a backup of this file in case you want to change it back (call it folderold.htt or something)
- 4. Open folder.htt with notepad
- 5. Delete the line <span id=MediaPlayerSpan>
- 6. Save your changes and close the file
This will kill the movie previews, not picture previews. However, the seekbar and frame will still be there.
Styled SSA subs seems to lag slightly in some DivX encoded MKV releases, what can I do?
This is an unfortunate result of the infamous b-frame lag that older versions of ffdshow (and DivX with "smooth playback" enabled) has. Upgrading to the newest CCCP (and not decoding DivX with DivX) will solve your problems as it now has a fixed ffdshow.
My non-English subtitles come out as random English letters and symbols!!
If your subtitle is in an East Asian language, go to:
- Go to Control Panel -> Regional & Language Options -> Languages
- Ensure that "Install East Asian Language Files", and "Install Files for Complex...Thai)" are ticked.
- Try your movie.
If it still doesn't work: You may need to install a "code page" for the encoding of your subtitle. The encoding is usually in the subtitle name, for instance mymovie.big5.cn.avi
You'll need a windows CD for this next bit. To install a codepage in XP go to:
- Control Panel -> Regional & Language Options -> Advanced
- In the box labelled "Code Page Conversion Tables", find your code page and make sure its ticked.
- If the box is ticked, the code page is installed. Press Apply or OK, and try your subs again.

How do I get rid of filters that show up in Insurgent, but can't be unregistered?
Such orphan entries can be removed with Filmerit:
Download Filmerit and run it. Press the question mark button (or just press F1) -> uncheck "Read-Only" -> a window pops up -> press Allow -> press Close. Now that we're back to the main window of the program, press the 3rd button from the left (or just press Ctrl+E) -> there should be a list of errors there -> press the first button from the left (or just press CTRL+W) to get back the full list of filters -> now press F12 to repair those errors. Note that there is no progress bar, so just wait a while. Close Filmerit.
The unused entries should now be gone.
Media player troubles
MPC crashes my Windows ME computer!
MPC crashes for some people who are using Windows ME. This is unfortunately not fixable. Either install CCCP with the Zoomplayer option or get Windows 2000 or XP.
What about other players not included in the CCCP?
Might or might not work. Refer to the Media Players article for a detailed list.
No. Just... no. Read the BSPlayer article for an explanation.
Advanced troubleshooting concepts
Care should be exercised when using these - if possible, ask #CCCP staff before attempting them. Some of these are only here to help you find more information that may help #CCCP staff to help you, and to spare us the trouble of explaining the same things over and over.
Checking which filters are loaded
- Open the file that's having problems and right-click the player.
- Choose the "Filter properties" submenu.
- Take note of all the entries in this submenu, except "Graph information".
In Media Player Classic:
- Open the file that's having problems and right-click the player.
- Choose the "Filters" submenu.
- Take note of all the entries in this submenu, except the filename one at the bottom.
Using GraphEdit to check what the filter graph looks like
This is a more advanced variation of the method above - it draws the entire filter chain for you to look at. First, download GraphEdit (Note: as of 2009-03-29 this link is dead, the latest archived file is at archive.org here: http://web.archive.org/web/20080113131916/http://www.cccp-project.net/nichorai/graphedit_build_2006.03.03.7z with MD5: d0cb834e18cb291316442850f88ebee7 and SHA1: d69f6155897cb6e854db11221733e42a62adc3d3) and unzip it to somewhere appropriate. Next:
- Run GraphEdt.exe and drop the problematic file on top of its main window.
- Take a screenshot of the graph. If you don't know how to do this, here's some simple instructions:
- Make sure you can see ALL of the graph without scrolling first. Drag the boxes around a bit if necessary.
- Find a key on your keyboard marked "Print Screen" and press it.
- Start Paint by going to Start -> Run... and typing mspaint, then pressing enter.
- Go to the Edit menu and press Paste.
- You now have a picture of what your desktop looked like when you pressed the Print Screen button. Save it by going to File -> Save as... Make sure you choose "JPEG file exchange format" in the lower dropdown menu before saving.
Nuking all old FFDShow settings
WARNING: This step should ONLY be attempted if you're really sure about what you're doing and why. ASK #CCCP STAFF FIRST!
- Go to Start -> Run... and type regedit. Press enter.
- In the window that pops up, use the tree view to the left to find some folders called
HKEY_CURRENT_USER\Software\GNU\ffdshow HKEY_CURRENT_USER\Software\GNU\ffdshow_audio HKEY_CURRENT_USER\Software\GNU\ffdshow_vfw HKEY_CURRENT_USER\Software\GNU\ffdshow_enc
- Delete the ffdshow, ffdshow_audio, ffdshow_vfw, and ffdshow_enc folders and close regedit.
- To get the CCCP default settings back you need to use the Reset All Settings option in the CCCP Settings or reinstall the CCCP.
Unregistering ALL DirectShow filters
This should only be done when everything else fails. DO NOT TRY THIS AT HOME, CHILDREN! Not unless a #CCCP staff member directly tells you so, at least.
ZoomPlayer 5 is required to do this. The process can make a Windows reinstall necessary or unneeded depending on how lucky you are.
- Start ZoomPlayer without having any file open.
- Go right click -> Options and make sure the advanced mode is enabled.
- Go to the System -> Filter Management tab and then press "Registered Filter Manager".
- Select all filters in the list using the shift key and press "Unregister Filter(s)". This will most likely show a dialog too big for your monitor so just press enter to proceed.
- After this nuking, you have to restore the system filters which you do by clicking "Re-Register System Filters".
- You're now done with this part and can close ZoomPlayer.
To re-register the filters included in the CCCP, all you have to do is open the settings, check "Re-Register Filters" and hit apply. If playback still fails we recommend reinstalling Windows.
Note that filters coming with any other program have to be re-registered if you plan to use them.
